To all whom it may concern? Be it known that I HERMAN F. Boson, 'a.

tates, residing at Millvale, in the county of Allegheny and State 'of Pennsylvania,.have invented a new and'. useful Improvement in Methods of Making Insolesffor Shoes, of which the followin is" a full, clear, and exact description, re erence being had to the accompanying drawings, forming part of this specification, in which v. V

Figure 1 is a plan view and Fig. 2 is a cross section of a-.finished insole made in accordance with my invention; and

. Figs. 3 and 4 are cross, sectional views I -In the particular method illustrated in the showing different stages of the operation.

My invention has relation to the method of making that class of insoles which are the under surfaces to which the welt and .upper are secured.

,sole. 50,

used in the manufacture of welt shoes, and which are provided with a stitching rib on Various methods have heretofore been devised for providing an insole with a stitching rib of this character, the rib in some cases being formed up from the material of the body of ,the insole, and in other cases comprislng a separate strip, cord, tape or the like, secured. to the insole and incased in 'a covering of canvas or other fabric. In insoles of the last named type, the tape, cord or other material has been secured to the insole by stitching, the stitches extending. This has been through. the cord or tape. 7 found objectionable owing to the fact that in securing the upper and welt to the insole,

the stitching of these parts frequently breaks a considerable number' of the stitches which secure the rib tothe insole. In so far as the strength of the shoe is largely dependent upon the security of the fastening of this rib, this is, of course, detrimental. The object of myinvention is to provide a -method of making an insole having a stitching rib applied thereto and which is free from any stitches extending through it, being secured to the insole by stitches which secure the fabri covering to the in-- Referring to the accompanying drawings in which I have illustrated the embodiment of my invention, the numeral 2 designates the bod ofthe insole, 3 th cord, tape r. other ri -forming member, and 4 the bottom covering of canvas, the latter incasmg the Specification of Letters Patent, Patented Sept. 24, 1918, Application filed August 7, 1917.

cord or tape 3, and covering the entire lower surface of theiinsole. Th1s coverin is se-- cured'to the insole by a double line 0 .stitching running around each side of the rib closely adj acent to thebase thereof.

In manufacturing my improved insole, I first provide a shaped insole body or blank, then apply the tape or cord thereto without securing means, and then apply the fabric covering 4, the latter having a coating of adhesive material on its inner surface. The covering fabric is then shaped over the cord or tape, after which it is stitched to the insole body. The manner of carrying out these several steps may be varied in detail.

accompanying drawings, I provide a block or'form 5, which is similar in outline to .the

contour of the-insole, but is of smaller dimensions, so that when applied to the bot-* tom surface of the insole it will just. occupy the space within the stitching rib. The fabric covering is then placed underneath this blockwith its edge portions upstanding, or partially upstanding, as shown in Fig. 3. The cord or tape 3 is then placed underneath the edge portions of the fabric, against and around the former. block, as also shown in Fig. 3. This tape may be; fed from any suitable holder through a suitable guide 6. 7 designates a presser. roller which follows the tape or cord and presses the edge p'ortions of the fabric down into contact with Fig, 4; The insolecan then be removed and 'the surface of the insole, and also in coaction withtheblock. properly shapes the canvas-over the tape, or cord, as shown in is ready for sewing on the double needle machine of well known type. The two linesof stitches 8 not only firmly secure the fabric covering to the insole, but also, of course,

hold the cord or tape securely in place with- I no - insoles, whichconsists in providing a shaped "blank,'then placingla covering on the blank,

then laying a stitc ing rib forming member between the covering and the blank along I the edge'of the blank and sha ing the covering around the stitching rib omning member, and then stitching said covering to the bod at each side'of the,rib, substantially as escribed. t
